A security-hardened, modern diagnostic tool built with Tauri v2 and React for Windows systems. Developed by Fara Technologies LLC for WindowsForum.com. This comprehensive utility features advanced security architecture, encrypted data storage, and a unique Hybrid AI analysis engine that leverages both OpenAI and local Phi Silica models on Copilot+ PCs.
- 38+ Diagnostic Tasks across 8 categories (System, Hardware, Storage, Network, etc.)
- Real-time System Monitoring with live CPU, memory, disk, and network visualization (Non-blocking)
- Encrypted Data Storage using AES-256-GCM with machine-specific keys
- Automated Issue Detection identifies critical problems (low disk space, firewall disabled, etc.)
- One-Click Fixes for common system issues
- Scan History & Comparison with intelligent change detection
- Multiple Export Formats (JSON, Text, HTML, Forum-formatted)
- Unified AI Service: Seamlessly switches between Cloud (OpenAI) and Edge (Phi Silica) models.
- Local AI (Phi Silica): Runs entirely on-device using the NPU on Copilot+ PCs (Windows 11 24H2+).
- Cloud AI (OpenAI): Fallback integration for standard PCs with function calling support.
- Context-Aware Analysis: Intelligent interpretation of diagnostic results and health scores.
- Command Injection Prevention with strict command whitelisting (12 allowed commands)
- PowerShell Script Filtering blocks dangerous operations, allows only diagnostic cmdlets
- Filesystem Access Restrictions limited to specific safe directories
- Encrypted Local Storage for sensitive scan data and API keys
- Secure OAuth2 Implementation with PKCE for WindowsForum.com integration
- Input Validation & Sanitization on all user inputs and system commands

The tool employs a Hybrid AI Strategy:
- Phi Silica (Local): Prioritized on supported hardware (Copilot+ PCs). It runs locally on the NPU, ensuring privacy and zero latency. It uses the
Microsoft.Windows.AI.TextAPI via Windows App SDK. - OpenAI (Cloud): Fallback for standard PCs. Requires an API key. Supports advanced function calling to autonomously select and run diagnostic tasks based on user queries.
- ✅ Non-blocking System Monitor: Decoupled slow polling operations (Disk, NPU) for instant UI responsiveness.
- ✅ Network Rate Fix: Corrected transfer rate calculation to eliminate spikes during startup.
- ✅ ✅ Accurate Swap Metrics: Switched to native PDH counters for true paging file utilization.
- ✅ Settings Persistence: Resolved issue with AI provider preference resetting to "Auto".
- ✅ UI Polishing: Enhanced network charts with simultaneous Upload/Download tooltips.
- ✅ Hybrid AI Engine: Integration of local Phi Silica models alongside OpenAI.
- ✅ Issue Detector: Automated identification of common system problems.
- ✅ Auto-Fixer: One-click remediation for supported issues.
- ✅ Health Model: Visual health scoring system.
- ✅ UI Updates: New Issues tab and improved navigation rail.
- v2.1.0 - Security Hardening & Encryption
